Big improvement on accelerating. Don't know on mileage yet.only one of fuel so far. Very easy to install. Most of my driving is off road.

Install on my 2005 Ford F350 6.0 was little over an hour. Biggest issue was the back nut on the back of the KN filter housing below the radiator fluid fill area. Very difficult to get to, but no issues on the install in general. Engine has good response, sound is about the same. Hoping to increase fuel economy but still in the testing process.

Did notice an increase in power. Noticed less lag from boost....at midrange rpm. Fuel economy probably increased about 2 miles average. Good buy. Recommended.
